Specification of Letters Patent.

Application filed August 20, 1913. Serial No. 785,742.

To all whom 'it may concern:

Be it known that I, THEODORE BARNES, a citizen of the United States, residing at Chariton, in the county of Lucas and State of Iowa, have invented certain new and useful Improvements in Explosive-Engines, of which the followingisa specification.

My invention relates. to improvements in internal combustion engines of the type wherein one or more cylinders are employed, which are bodily rotated during the operation of the engine, such rotary movement being effected by the reciprocatory movement of the pistons therein.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of an engine embodying my invention, parts being shown in section and parts omitted, Fig. 2 is a side elevation of one cylinder, taken at a right angle to the showing in Fig. 1, Fig. 3 is a detail elevation of a guide, Fig. 4 is a central vertical transverse sectional View through the engine, Fig. 5 is a detail section through the inlet and exhaust pipes of the cylinder, and, Fig. 6 is a diagrammatic view of a cam track.

In the drawings, wherein for the purpose of illustration, is shown a preferred embodiment of my invention,.the numeral 9 designates a relatively stationary frame, having connection with bearings 10 and 11, as shown. The bearing 10 receives a main driving shaft 12, preferably operating in engagement with bearing rollers 13, as shown. Rigidly mounted upon the outer portion of the main driving shaft 12 is a ring 14, preventing the inward longitudinal movement of the shaft 12. Rigidly mounted upon. the

inner end of the main driving shaft 12 by any suitable means, such as a key or the like, is a central rotatable support or hub 15. As more clearlyshown in Figs. 1 and 4, the numeral. 16 designates an annular casing which is preferably formed integral with the hub 15. This annular casing is provided with one or more tubular sockets 17 which are preferably not exactly radially disposed with relation to the hub 15 but are slightly inclined forwardly toward the direction of rotation of the engine, with relation to said radii. This degree of angularity or inclination of the sockets 17 may be varied considerably. n The numeral 18 designates explosion cylinder or cylinders, there being referably a plurality of the same correspon ing in numher with the sockets 17, and havin their inner ends inserted within the tubu ar sockets 17 and held therein b any suitable means. The cylinders 18 are old by the sockets 17 in the same angular or inclined position with relation to the hub 15. These cylinders are identical so that a description of Patented Nov. 3, 1914.

one will sutlice for all. Each explosion cylinder 18 is preferably provided upon its exterlor with coolin fins or ribs 19, as shown. The outer end 0 the cylinder 18 is closed by a head 20, detachably connected therewith' by means of bolts 21 or the like, whereby access may be had to the interior of the same. ,The head '20 is preferably provided with a pressure relief cook 22, of any well known or preferred ty e. The cylinder 19 is provided with a spark plug 23, preferably arranged, as shown. As more clearly shown in Figs. 1 and 2, the cylinder 18 is provided adjacent its closed head 20 with laterally extending inlet and exhaust chambers 24 and 25, there being upwardly opening valves 26 and 27, which close openings that lead into the same. The valves 26 and 27 are carried by reciprocatory rods 28 and 29, operating through fixed guide sleeves 30, as shown. Surrounding the upper portion of the valve rods 28 and 29 are compressible and expansible coil springs 31, 32, engaging rings 32' and 33, which are rigidly mounted upon the valve rods 28 and 29. The springs 31. and=3-2 normally hold the valves 26 and 27 seated.

The numeral'34 designates a horizontal finger or operating element, having its opposite ends forked to receive the rods 28 and 29, the same engaging the lower ends of the rings 32 and 33. The operating element is fulcrumed between its ends upon a fixed rod 34 or the like. Rigidly connected with the operating finger 34 equi-distantly' between the ends thereof, is a depending lever 35, having pivotal connection, as shown at 36, with a horizontal reciprocatory rod 37. The rod 37 is pivotally connected with a slide 38, mounted within the guide 39. It is obvious that when the lever 35 is swung in one direction it will open one valve and swung in the opposite direction the same will open the other valve.

The hub 15 is provided with an annular charge or gas holding chamber 40, having its outer side closed by means of an annular plate 41, (see Fig. 5) which is stationary and is rigidly connected with the bearing 10, by any suitable means. Connected with plate 41 is agas supply conduit 41*. The hub 15 is preferaiol provided with packing rings 42, which shdably engage the annular plate 41 to form a gas tight joint without excessive friction. The annular plate 41 may be formed in one or more parts. Rigidly connected with the annular plate 41 is an outer annular plate 42, which may be formed of one or more parts. This outer annular plate has an annular cam track 43, rigidly connected therewith.

The numeral 44 designates a gas supply port, having communication with the gas chamber 40, and with an inlet pipe 45, which discharges into the inlet chamber 24.

The numeral 46 designates an exhaust pipe, which leads into the exhaust chamber 25. The inner end of the exhaust pipe 46 is connected with an extension 47, which operates within an annular exhaust pipe 48, the same discharging therein. The annular exhaust pipe 48 has connection with an outlet pipe 49, to which may be connected a mufller, if desired. The annular exhaust pipe 48 is provided with annular receiving packing rings 50 which slidably engage a side plate 51, attached to the ring 16.

. .Mounted to reciprocate Within the cylindiers 18 are preferably hollow pistons 52,

provided with oil openings 53. Pivotally connected with the pistons 52, as shown at 54 are pitmen 55. One pitman 55 is rigidly connected with a sleeve 56 while the other pitmen 55 are pivotally connected therewith,

as shown at 57. The sleeve 56 is rotatably mounted upon a stationary stub-shaft 58 and is held against longitudinal movement in one direction by a preferably detachable ring 59. The stub-shaft 58 is mounted within the bearing 11 and is held therein by a nut 60, as shown The stub-shaft 58 is eccentrically arranged with relation to the main drivingsha'ft 12'. T'Tt is obvious that the reciprocatory movement of the pistons 52 will effect the rotation of the cylinders 18.

The rings 63,.ard provided with segmental openings 64, if'eceiving fans 65, which are adapted to be ,angu-h-irly adjuste y-being turned upon their longitudinal a "f Each fan 65 is rigidly mounted upon a dock-shaft 66, which is radially disposed and has its opposite ends mounted within fixed bearings 67, as more clearly shown in Fig. 4. Each rock-shaft 66 has a pinion 68 rigidly connected therewith, which is engaged by the end I of a transverse rack-bar 69. The rack-bar 69 is connected with a laterally extendin arm 70which-is connected with a latera ly extending operating rod 71. The rod 71 is provided with an outwardly extending tooth 72, shdably mounted within a grooved relatively starotation or turning of the ring 73, I attach thereto a toothed segment 7 5, whichis engaged by a pinion 76, which is operated by an exteriorly arranged hand wheel 77. It is thus seen that by turning the hand wheel 77 the blades 65 may be turned upon their longitudinal axes or angularly adjusted so that they will deflect the desired amount of air into the casing.

As more clearly shown in Fig. 6, the stationary cam track 43 is provided with an intermediate or central groove 78 and inner and outer grooves 79 and 80. The intermediate groove 78 makes almost a complete circuit of the member 43; the groove 80 extends about one-half way about it; and the groove 7 9 extends almost one-half way around the member. The remaining distance required to complete the two circuits of the member 43 is taken up in crossing from one groove to the other. shown in Fig. 3, the slide 38 is provided with -a pin 81, upon which is suitably mounted a block 82, adapted to travel in the grooves 78, 79 and 80. A spring 83 surrounds the pin 81 and serves to force the block outwardly to engage the bottom wall of the grooves. The groove 80 where it crosses the groove 78, at point 84, is made deeper whereby the block 82 will be safely carried over.

The charge in each cylinder is fired when the cyl nder has made two complete revolutions, whereby each engine unit is a four cycle engine, such firing of thecharge being efl'ected by any suitable means. I

In the operation of the engine, (see Fig. 6). when the block 82 is in the groove 78, both-the exhaust and inlet valves 26 and 27 will be closed; when the block 82 is in the groove '80 the exhaust valve 26 will be opened and inlet valve 27 closed; and when the block 82'is in groove 79 the exhaust valve 26 will be closed and the inlet valve 27 opened. Starting the block 82 at the pointlOO in groove 78, ,both valves will be held closed by their springs, during the compression and working strokes. When the block 82 leaves the groove 78at about the point 101 and passes into the groove 80, it opens the exhaust valve and holds it open the required length of time, that is until the block reaches the point 102 in the groove 80. At the point 102 it leaves the groove 80, whereby the spring will at once close 'the exhaust valve, and passes into the groove 79, to open the intake valve 27 immediately after the closing of the exhaust valve. The intake valve is held open until the slide 82 reaches the oint 103 or. until a suliicient amount of gas as entered the cylinder, when the inlet valve is allowed to again close for the compression and working strokes by block 82 assing into the groove 78. When each cy inder has made two revolutions, the charges are fired.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub joined claims.
